If the inclined angle between two plane mirrors is 60, Calculate the No. of Image formed.

The inclined angle between the two plane mirrors is $\theta = 60^\circ$.

The number of images ($n$) formed by two plane mirrors inclined at an angle $\theta$ is given by the formula:

This formula is used when $\frac{360^\circ}{\theta}$ is an even integer, or when it's an odd integer and the object is placed symmetrically. For an even integer, it always applies.

The number of images formed is $\boxed{5}$.

The diagram shows a mirror surface (horizontal line) and a normal (vertical line perpendicular to the mirror).
Angle M is the angle of incidence (between the incident ray and the normal).
Angle N is the angle of reflection (between the reflected ray and the normal).
The angle between the reflected ray and the mirror surface is given as $24^\circ$.

The normal is perpendicular to the mirror surface, so the angle between the normal and the mirror surface is $90^\circ$.
Therefore, the angle of reflection (N) and the angle between the reflected ray and the mirror surface ($24^\circ$) sum to $90^\circ$.

According to the Law of Reflection, the angle of incidence is equal to the angle of reflection.

The angles are $\boxed{M = 66^\circ, N = 66^\circ}$.
